Top-seeded Long Beach State advanced to the semifinals of the Big West Women's Tennis Tournament for the 16th straight year after defeating eighth-seeded Cal Poly, 5-0, in quarterfinal action at Indian Wells Tennis Garden Thursday.

The Beach will play No. 4 seed Hawai‘i at 9 a.m. for a spot in the championship match. LBSU has reached the championship match in every season since 2001, a span of 15 straight appearances.

Cal Poly took LBSU to the brink of losing the doubles point. The Mustangs picked up a win at No. 1 with Zoe Oedekerk and Dane Joubert earning a 6-3 decision against Laura Eales and Hayley Thompson. The Beach responded at No. 2 when Maeva Razakasoa and Julie Gerard squeezed past Bryn Bacharach and Ilana Oleynik, 6-4. At No. 3, Ebba Unden and Alex Jones faced a 5-2 deficit against Abby Bacharach and Molly Reed, but rallied to win the final five games to take a 7-5 victory and give LBSU the doubles point.

From there, the Beach seized control of the match with three straight singles wins, losing a total of five games along the way.

For the third straight year, UC Santa Barbara defeated UC Davis in the quarterfinals of the Big West Women's Tennis Tournament, advancing to the semifinal round for the fifth year in a row.

The second-seeded Gauchos yielded a total of just seven games throughout doubles and singles to earn the 4-0 victory over the No. 7 seed Aggies.

In doubles play, Amanda Atanasson and Lou Adler won their No. 3 match by a 6-0 count. The Gauchos clinched the doubles point when the nation's No. 24-ranked duo, Stefani Stojic and Palina Dubavets, took home a 6-1 victory at No. 1.

Dubavets was off the court first in singles play, capturing her match 6-0, 6-1 against Kristy Jorgensen at No. 2. Atanasson followed suit with a 6-1, 6-0 victory at No. 5 over Kamila Kecki. UCSB clinched the contest at No. 4 as Jaimee Gilbertson powered her way to a 6-3, 6-1 victory over Tiffany Pham.

UCSB now seeks a berth in the championship match for the second straight year, but must first get past No. 6 CSUN, which upset third-seeded Cal State Fullerton on Thursday morning. The Gauchos are now 16-7 overall this season.

Avenging a loss in the regular season, No. 6 CSUN pulled off a thrilling 4-3 upset over No. 3 seed Cal State Fullerton in a three and a half hour back-and-forth affair at Indian Wells Tennis Garden Thursday. The quarterfinal victory sets up a showdown against No. 2 UC Santa Barbara in Friday's Big West Women's Tennis Championship semifinals.

In a match where neither team led by more than a point the entire way, the Matadors leaned on the strength of the bottom of their singles order to eke out the victory.

Ki Kim clawed her way to a 6-2, 4-6, 6-3 win at No. 5 singles to clinch the match for CSUN against CSF's Masako Makiba. Setting up those heroics was Mari Taslagyan at No. 6, with the Matador junior gutting out a 3-6, 6-1, 6-4 win against Danielle Pham to tie the match at three apiece. Trailing Pham 4-3 in the third set, Taslagyan reeled off three straight games to end the match.

After the two teams split at No. 1 and No. 3 doubles, CSUN's No. 2 duo of Vivian Lin and Skyla Alcon outlasted their Titan counterparts, Makiba and Karla Portalatin to win what would end up being a crucial doubles point. Lin and Alcon fought to a 7-6 (9) tiebreak victory.

Camille DeLeon tied the match at 1-1, defeating Kristen Poei 6-0, 6-4 at No. 4, but Alcon responded with a 6-3, 6-3 triumph over Portalatin at No. 3 to give the edge back to the Matadors.

Alexis Valenzuela then stepped up for the Titans and took a 6-3, 6-3 win over Mickey Hsu at No. 1 to equalize the match again at 2-2. Giving the Titans their first lead, Sarah Nuno grabbed a 6-4, 6-2 victory against Lin at No. 2 for a 3-2 advantage.

But Taslagyan withstood Pham's quest to finish off the match and the Matadors moved onto the semifinals for the second year in a row. CSUN takes a 10-12 record into Friday's match with UCSB.

Hawai‘i controlled its quarterfinal matchup against UC Irvine from start to finish, notching a 4-0 victory to finish off quarterfinal action in the Big West Women's Tennis Championship Thursday at Indian Wells Tennis Garden.

The No. 4 seed Rainbow Wahine won at No. 1 and No. 2 in doubles to quickly snatch the doubles point, then took victories at Nos. 2, 5 and 6 at singles to clinch their third semifinal berth in the last four years.

Klara Pribylova, playing at No. 5 singles for the first time all year, knocked off Mazy Watrous by a 6-2, 6-1 score to put UH up 2-0. Freshman sensation Marina Hruba then improved to 11-0 at No. 2 singles with her 6-3, 6-0 win over Dvali.

UH improved to 12-9 on the season. The Rainbow Wahine will need to stage an upset of top-seeded Long Beach State in Friday's 9 am semifinals to advance to their first championship match. LBSU is 36-1 all-time at Indian Wells Tennis Garden.
